Pallet truck

ABSTRACT

The invention relates to a pallet truck comprising a lifting device, which is mounted on the axle of two wheels, and having a supporting frame, which is mounted on two rollers, provided with two bearers and is displaceably connected to the lifting device. The lifting device has a lifting pump mounted on a console which is placed on a support that is, in turn, mounted on the axle extending between both wheels. A rod is mounted on the lifting pump, and the lifting pump has a piston rod whose head projects upwardly out of the housing of the lifting pump. A roller is mounted at the rear end of each bearer, and the bearers are connected to one another at the front end via a crossbar. A holding frame having a socket is provided on the front end of the bearers and is mounted in an articulated manner on the head of the piston rod. A two-armed linkage is mounted on both sides of the console. The front arms of this linkage are connected to the console and the rear rod of the linkage is connected to the allocated roller each of which being connected in a manner that permits them to pivot. According to the invention, the pallet truck can be disassembled into two equally heavy parts, and the disassembled parts can be reassembled to form the pallet truck.

The invention relates to a pallet truck having a lifting device mountedon the axle of two wheels, and a supporting frame mounted on tworollers, having two bearers, which is movably connected with the liftingdevice, whereby the lifting device has a lifting pump arranged on aconsole, which is arranged on a support that is mounted on the axlebetween the two wheels, and whereby a rod is arranged on the liftingpump and the lifting pump has a piston rod, the head of which projectsout of the housing of the lifting pump, in an upward direction, andwhereby a roller is arranged at the back end of the two bearers, in eachinstance, and the bearers are connected with one another at the frontend by way of a crossbar, and a holder frame having a socket is providedat the front end of the bearers, which socket is mounted on the head ofthe piston rod, in articulated manner, and whereby a two-armed linkageis arranged on both sides of the console, the front arms of which areconnected with the console, and the back rod of which is connected withthe related roller, in each instance, so as to pivot.

In the case of such a manual pallet truck consisting of a lifting deviceand a supporting frame, the lifting device and the carrier frame areconnected with one another in movable and inseparable manner. As aresult, the manual pallet truck is heavy in weight and difficult tohandle. It can be carried or lifted only by at least two persons. Inthis connection, the two persons are also exposed to significant risksof accident. This means that the manual pallet truck cannot be carriedup a stair step or down a stair step by only one person, so that thepallet located on the manual pallet truck cannot be brought to thedesired location with the manual pallet truck if there are heightdifferences that must be overcome. In the case of a manual pallet truckas an industrial truck, such movements are generally not required. Inspecial cases, however, this results in significant difficulties,because the pallet truck is stable and therefore heavy in weight. For anindustrial truck, the amount of the weight is without significance, to agreat extent, because it is only driven on a single plane, in otherwords not on planes of different levels.

The invention is based on the task of configuring a pallet truck in sucha manner that it can be easily carried by one person if heightdifferences are to be overcome.

This task is accomplished in that the head of the piston rod and thesocket is secured against falling out by means of an easily releasablescrew, and that the front arm of the linkage, in each instance, isarranged so as to rotate on the console, by means of a socket pin, andthat the socket pin is secured against falling out by means of a holderpin.

In this manner, one arrives at a pallet truck of the type statedinitially, which fully fulfills the aforementioned task. The screwguided by the socket can be released without using tools, because a wingnut is screwed onto the free end of the screw. The two socket pins onthe console can also be easily released without using tools. As aresult, there is the possibility of very quickly separating the liftingdevice and the supporting frame, with three manipulations, so that thereare two parts, namely the lifting device, on the one hand, and thesupporting frame, on the other hand. The lifting device alone can beeasily carried from one plane to another plane, by way of a stair step,as can the supporting frame.

The two parts, namely the lifting device and the supporting frame, canbe connected with one another again by means of three simplemanipulations, after they have been brought to a different location.

Furthermore, the advantage of being able to divide the manual pallettruck into two parts consists in the fact that the manual pallet truck,when it is broken down into its two parts, can easily be lifted into astation wagon, passenger car, small truck or large truck, by only asingle person, and stowed away there.

Assembly or disassembly of the pallet truck takes place without tools,and no individual parts have to be stored, which could possibly be lost.Assembly as well as disassembly are performed by a single person, duringa short time of only a few seconds.

In a further embodiment of the invention, it is provided that thelifting device is configured as a thrust piston pump, the piston rod ofwhich is mounted to be axially displaceable in the pump housing, andprojects out of the pump housing in an upward direction. In this way,the supporting frame can be lifted and lowered with the required lift.

It is advantageous if the screw in the socket is passed through the sidewalls of the socket and a ring-shaped constriction in the top part ofthe piston rod.

It is practical if the socket pin is mounted in the console so as torotate, and the holder pin is guided through the console and aring-shaped constriction of the socket pin.

Furthermore, it is recommended that the screw and the holder pin as wellas the socket pin are connected with one another by means of a chain.

It is practical if the pallet truck is configured in such a manner thata set of wheels having two wheels and an axle is provided, whereby asupport is mounted to rotate on the axle, which support carries theconsole with the pump device.

A rod for lifting, lowering, pulling, pushing and steering the pallettruck can be provided on the console, which rod activates the pumpdevice by being pivoted in the vertical plane.

To reduce the weight of the pallet truck, the bearers, the holder frameof the supporting frame, as well as the rod have openings or recesses.

The task underlying the invention is also accomplished in that thepallet truck can be broken down into two parts of approximately equalweight, and that the disassembled parts can be re-assembled to form thepallet truck.

It is practical if the solution to the task consists of being able tobreak the pallet truck down into the lifting device and the supportingframe, and that the lifting device and the supporting frame can bere-assembled to form the pallet truck.

In this way, the pallet truck can easily be broken down into the liftingdevice and the supporting frame, if necessary, so that subsequently, thelifting device can be brought to a different location by a singleperson, and the supporting frame can also be brought to the samedifferent location by the same person, where the lifting device and thesupporting frame can be easily re-assembled to form the pallet truck.

The two parts, namely the lifting device and the supporting frame, canbe very quickly connected with one another again, after they have beenbrought to a different location.

In a further embodiment of the invention, it is provided that thelifting pump is configured as a thrust piston pump, the piston rod ofwhich is mounted to be axially displaceable in the pump housing, andprojects out of the housing in an upward direction. In this way, thesupporting frame can be lifted and lowered with the required lift.

It is practical if the pallet truck is configured in such a manner thata spring-loaded snapper is provided in the holder frame, at the level ofthe piston rod head, which acts perpendicular to the piston rod axis,i.e. horizontally, which snapper is brought into and out of engagementwith a constriction of the piston rod head.

It is recommended to provide a horizontally directed accommodationjournal on the console, on both sides, in each instance.

The pallet truck can also be configured in such a manner that a togglelever is mounted, in articulated manner, on the bearers, in eachinstance, each toggle lever having a bearing accommodation, open towardsthe front, to accommodate the accommodation journal, at its front end.

In addition, a holder bracket can be arranged so as to pivot, in thefront region of the toggle lever, which bracket is to be pivoted overthe bearing accommodation.

It is practical if the pallet truck is configured in such a manner thata set of wheels having two wheels and an axle is provided, whereby asupport is mounted to rotate on the axle, which support carries theconsole with the pump device.

A rod for lifting, lowering, pulling, pushing and steering the pallettruck can be provided on the console, which rod activates the pumpdevice by being pivoted in the vertical plane.

To reduce the weight of the pallet truck, the bearers, the holder frameof the supporting frame, as well as the rod have openings or recesses.

The one part of the pallet truck consists of the handle, the steeringrod with the pump, the piston rod, and two wheels, while the other partof the pallet truck consists of the supporting frame, the toggle lever,two pulling rods, and two or four rollers.

Within the bearing bar 127, the piston rod head 137 is mounted in asuitable socket. At the level of the constriction 138 of the piston rodhead 137, a snapper 158 is provided to move horizontally. The snapper158 is mounted in two bearings 159 and 160, so it can be displacedlengthwise, and is subject to the pressure of a spring 161. The snapper158 can be brought into and out of engagement with the constriction 138by means of a handle 162.

In FIG. 14 a, the snapper 158 is in the closed position, in which itengages in a constriction 138 of the piston rod 136 and thereby arotating but rigid connection between the piston rod 136 and the bearingbar 127 is guaranteed, i.e. a rigid, rotating connection between theholder frame 101 and the lifting device 102.

In the representation according to FIG. 14 b, the snapper 158 is pulledout of the constriction 138 of the piston rod 136, so that the pistonrod 136 and the bearing bar 127 can be separated from one another.

As is evident from FIGS. 10 and 17, accommodation pins 164 and 165 areprovided at both sides of the traverse 163. At the front end of thetoggle lever 157, as is evident from FIG. 9 a, a bearing opening 166that is open towards the front is provided, which opening can be closedand opened by means of a bracket 167 that is arranged to pivot on thetoggle lever 157. In this connection, FIG. 9 a shows the open positionand FIG. 9 b shows the closed position.

According to the representation in FIGS. 10 and 17, the one bracket 168is in the open position, while the bracket 169 arranged opposite theformer is in the closed position and surrounds the accommodation pin164.

FIG. 15 shows the toggle lever 157, at the front end of which thebracket 168 is mounted to pivot on the axis 170. In the closed state ofthe bracket 170, as shown, the accommodation pin 165 is rigidly arrangedbetween the bearing opening 186 of the toggle lever 157 and the bracket165.

In the closed state of the brackets 164 and 165, the lifting device 102and the holder frame 101 of the pallet truck are rigidly connected withone another, but so as to rotate.

In the open state of the brackets 168 and 169, the toggle lever 157 andthe accommodation pin 165 can be separated from one another. This meansthat the lifting device 102 and the holder frame 101 of the pallet truckcan be separated from one another.

If the pallet truck shown in FIGS. 8 and 12, in which the lifting device102 and the holder frame 101 are rigidly connected with one another, soas to rotate, in the region of the piston rod 136 and in the region ofthe two accommodation pins 164 and 165, are supposed to be separatedinto the lifting device 102 and the holder frame 101, as they are shownin FIGS. 11 and 13, first the snapper 158 is brought out of engagementon the handle 162, and the bar 127 is removed from the piston rod 138.Subsequently, the two closed brackets 168 and 169 are opened, so thatthe accommodation pins 164 and 165 are freed and the toggle lever 157can be removed from the accommodation pins 164 and 165. With this, thelifting device 102 and the holder frame 101 of the pallet truck areseparated from one another and can also be transported independent ofone another, and carried by a single person.

If the separation of the pallet truck into the lifting device 102 andthe holder frame 101 is supposed to be made retroactive again, thelifting device 102 is tilted towards the holder frame 101 so far thatthe pin head 137 can enter into the socket of the bearing bar 127.Subsequently, the lifting device 102 is set perpendicular again, so thatthe bearing opening 166 of the toggle lever 157 accommodates theaccommodation pins 164 and 165. Afterwards, the two brackets 168 and169, which were open until then, are closed again, so that in this way,the original state of the pallet truck is restored, namely the liftingdevice 102 and the holder frame 101 are rigidly connected with oneanother, in articulated manner.
